What You'll Do

We're looking for an engineer who likes solving hard problems, not just writing code.

You'll combine software engineering + quantitative analysis + financial logic + AI to build production systems supporting complex mortgage and financial operations.

You'll get to:

Build production-grade software and expert systems

Turn complex business knowledge and decision-making into automated system logic

Work with large financial and mortgage servicing datasets

Build SQL-based systems, ETL pipelines, APIs, and automated workflows

Apply optimization, simulation, statistical modeling, and operations research

Develop solutions involving cash flow, financial models, risk, reconciliation, and exception management

Automate processes that currently require significant manual analysis

Build systems designed for accuracy, validation, traceability, and auditability

Work directly with developers, operations teams, financial professionals, and subject matter experts

Help enhance and expand PMSI's proprietary Q™ technology platform

The role includes building expert systems that integrate rules-based logic, quantitative models, and decision-support algorithms into PMSI's technology platforms.

Yes, You'll Work With AI

We're looking for someone who knows how to use AI as an engineering tool without blindly trusting the output.

You'll have opportunities to:

Use AI coding agents and AI-assisted development tools

Apply AI to coding, testing, debugging, documentation, and modernization

Build controlled AI/agentic workflows using APIs, data, business rules, and internal systems

Validate, test, and refine AI-generated code

Build appropriate controls, monitoring, and human oversight into AI-enabled solutions

What You Bring

Technical Skills

Strong C#/.NET, C++, or comparable object-oriented development

Strong SQL and/or MongoDB

Experience with APIs, ETL/data pipelines, automated workflows, and data-intensive applications

Experience using AI coding agents or AI-assisted development tools

Knowledge of quantitative analysis, optimization, simulation, statistical modeling, or operations research

Just as Important

Excellent analytical and problem-solving skills

Strong professional verbal and written communication

Ability to explain complex technical concepts clearly

Comfortable asking questions and working directly with subject matter experts

Ability to translate business problems into technical solutions

Strong documentation skills

Detail-oriented and quality-focused

Comfortable working in a collaborative, fast-moving environment

Education & Experience

Required

Bachelor's degree in Operations Research, Financial Engineering, Applied Mathematics, Computer Science, Industrial Engineering, or related field

Typically 3–7 years of relevant experience in software development, quantitative analysis, or analytical technology development

Demonstrated experience building production-grade systems

Exceptional technical and analytical ability may allow some flexibility in years of experience

Nice to Have

Advanced degree in a quantitative field

Structured finance or mortgage servicing experience

Financial modeling experience

Serverless ETL or AI/ML deployment experience

Experience putting quantitative or analytical methods into real production software

You'll Probably Love This Role If...

You're a software engineer at heart

You genuinely enjoy difficult analytical problems

You like figuring out why something works, not just how to code it

You enjoy turning messy processes into structured systems

You can move between code, data, math, business logic, and people

You want to build things that actually make it into production

When someone says, "It's complicated, you just have to know how it works," your reaction is: "Okay...how do we teach the system to know that?"

That combination of software engineering, quantitative problem-solving, knowledge engineering, systems thinking, and practical innovation reflects the success profile for this position.

Ready for a Challenge?

If you're looking for a fully remote development job, this probably isn't the right fit.

But if you want to be in the room, solving difficult problems with a team, building new technology, experimenting with AI, and seeing your work make an impact, we'd like to hear from you.
